Olanzapine, which is a second-generation antipsychotic drug, can cause metabolic side effects, including hyperphagia, weight gain and acute hyperglycaemia.
Does olanzapine lower metabolism?
Indeed, reduced body temperature after olanzapine treatment may generate many of the known side effects of this antipsychotic drug. The authors’ new findings also demonstrate that olanzapine alters peripheral glucose metabolism, which may contribute to impaired insulin sensitivity.
Does olanzapine increase metabolism?
Three randomized, double-blind, controlled trials support the efficacy of olanzapine in patients with newly diagnosed psychosis. However, metabolic data from these trials showed that olanzapine was also associated with significant increases in weight, body mass index (BMI), and treatment-emergent metabolic syndrome.
Can you lose weight while on olanzapine?
Results: Patients incurred an average weight loss of 2.7 +/- 0.7 kg (p = 0.001) after switching patients from olanzapine SOT to olanzapine ODT at 12 months. Peak weight loss was observed at 6 months; however, significant weight loss was achieved as early as 3 months.
Do antipsychotics slow down metabolism?
In addition to weight gain, antipsychotics are also known to impair glucose metabolism, increase cholesterol and triglyceride levels and cause arterial hypertension, leading to metabolic syndrome.
How much weight will I gain on olanzapine?
The mean weight gain was 7.9 kg during the 12-week period of olanzapine treatment, with patients gaining 2.4, 4.0, and 1.5 kg at the first, second, and third 4-week period, respectively. Female patients were more likely to gain weight (P < 0.001), with 9.19-kg mean weight gain during the study period compared with 5.90 …
Is olanzapine anti inflammatory?
Olanzapine (OLZ) is an atypical antipsychotic drug that also has mood-stabilizing effects. The mechanism of action of OLZ is not fully understood. Accumulating data suggest that inflammation plays a role in the pathophysiology of mental disorders and that psychotropic drugs exhibit some anti-inflammatory properties.
Does everyone gain weight on olanzapine?
The results of the study revealed that there is a significant gain in weight with olanzapine, which is related to age ≥40 years and sex; women ≥40 years of age are more prone to gain weight in comparison with those <40 years and men of any age group. The weight gain is not related to the dose of olanzapine and BMI.
Is 2.5 mg of olanzapine effective?
It hasn’t been confirmed that olanzapine is safe and effective for the treatment of treatment-resistant depression in people younger than 18 years. Typical starting dosage: 2.5–5 mg olanzapine with 20 mg fluoxetine per day. Dosage increases: Your doctor may carefully increase your dosage as needed.
What are the side effects of olanzapine?
Olanzapine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- dizziness, feeling unsteady, or having trouble keeping your balance.
- unusual behavior.
- difficulty falling asleep or staying asleep.
- difficulty walking.
Does 2.5mg olanzapine cause weight gain?
Clinically significant weight gain was observed across all baseline Body Mass Index (BMI) categories. Following short-term treatment (median duration 47 days), weight gain ≥7% of baseline body weight was very common (22.2 %); ≥15 % was common (4.2 %); and ≥25 % was uncommon (0.8 %).
Is there an alternative to olanzapine?
It has been suggested that risperidone is associated with a lower propensity for abnormalities in glucose‐insulin homeostasis than clozapine4, 8 and olanzapine. This case suggests that risperidone may be an alternative for patients with hyperglycemia, which is associated with atypical antipsychotic drugs.
What is the best antidepressant for weight loss?
“We found that bupropion is the only antidepressant that tends to be linked to weight loss over 2 years,” study leader David Arterburn, MD, Group Health Research Institute, Seattle, Washington, said in a Group Health Research Institute news release.
How do you avoid weight gain on antipsychotics?
The main approaches to managing weight with antipsychotics are: Ensure that the risk of weight gain, and other side effects, are considered when choosing an antipsychotic. Wherever possible use drugs with a lower risk of weight gain. Monitor weight and Body Mass Index (BMI) during antipsychotic treatment.
How much weight do you gain on antipsychotics?
Meta-analysis found that patients receiving standard doses of atypical antipsychotics for 10 weeks gained a mean of 9.79 lb with clozapine, 9.13 lb with olanzapine, 6.42 lb with sertindole, 4.6 lb with risperidone, and 0.09 lb with ziprasidone.
Will I lose weight after stopping antipsychotics?
Weight loss may occur once a person stops taking their medication. However, this will depend on the drug in question and the individual. People who stop taking antipsychotics usually see gradual weight loss. Stopping a medication, however, is not always possible, and it can sometimes have serious repercussions.
